Maybe it's because they have a greater chance of living in poverty, and poverty is correlated with high crime rates. Or maybe it's because they live alone and have no one to check for them at 10pm when everyone else knows where their children are.
If you're single, you need to be vigilant because you're the only one looking out for you. Take care of yourself by following these tips:
How to Protect Yourself When You're Out
1. It's an oldie but goodie: Go out with groups as much as possible, especially at night and when in unfamiliar surroundings. If you need to leave the group for any reason, tell them where you're going. If you're going out alone, tell a roommate, family member, or friend where you'll be and when you expect to be back. If you won't be home too late, arrange to call them when you get in and ask them to call you if they don't hear from you.
2. If you're driving, park in a well-lit area as close to your destination as possible. Be aware of this even in the day. You might stay out later than you planned.
3. Keep your wallet or handbag on you at all times. Don't rummage through it in public. Take it with you to the restroom; friends tend to get distracted and won't always keep an eye on it even when they promise to. Be wary of anyone who bumps into you. It's a favorite technique of pickpockets. Keep most of your cash in the wallet, but leave a little in your pocket. That way, if the wallet is stolen, you'll have enough for an emergency phone call or ride home.
4. Never leave a drink unattended. As with a bag, beware of leaving your drink in the company of friends, especially if they're drunk and rowdy. They may have good intentions, but intentions don't deter thieves. Don't drink to excess if you're going home alone, even if you're not driving. You need your wits to be your sharpest weapon when you leave the bar or party.
5. This shouldn't even need to be said, but don't go home with a stranger, especially if you're a woman. Don't even go home with a friend of a friend you just met. Date rape happens and is, in fact, more frequent than rape by a stranger. If he likes you tonight, he'll like you tomorrow, and if he doesn't, it would've been a one-night stand anyway. If you've just met someone who wants to get your number, get his or hers instead. If you must give out your number, make it your cell. In an age in which someone can order up a detailed background check from USSearch as fast as they can order a Happy Meal, anyone can track down your address from a publicly listed land line. Keep your personal info personal and don't reveal your place of business or even your last name until you're beyond the getting-to-know-you stage.
6. When walking alone at night, carry an alarm, a can of mace, pepper spray, an umbrella, or, at the very least, your keys. Don't just tuck them away in your bag and forget about them. Grip them in your palm, on the ready.
7. Get on the phone with someone and stay on until you're safe in the car or at home. While talking on the phone won't prevent a criminal from trying to abduct you, at least you'll be able to alert your loved one on the other end of the line, and cells have the added advantage of GPS tracking to pinpoint your location. Put your police precinct or fire department on speed dial in case you can't fumble for 911 in the dark.
8. If you live in a city and don't drive, don't take the bus or train after about 11:00pm. Always take a cab--a licensed one, not a gypsy cab. When you get out, ask the cab driver to wait till you're inside.
9. If you're leaving an establishment late at night by yourself and the parking lot is deserted, ask security or an employee to walk you to your car. Parking lots are among the most common sites for rape and abduction. Don't worry about looking silly. Embarrassment is fleeting. Death is not.
